The other day I asked my husband "what should I bake this weekend?". His answer was not, surprisingly, Cinnamon Buns. Instead it was "I don't know... let's Google 'dessert' and you can make the first thing that comes up.". If that sounds like a fun game, I hate to break it to you, but unfortunately it's not. I was saying things from "I don't even know what that is" to "I don't have enough time to make that!", and before we knew it, 'the first thing that came up on Google' slowly turned into the 30th thing and we I still hadn't agreed to one. In the end we settled on something s'mores flavored, and if I'm being completely honest, I don't even know how that happened. I guess I was just so desperate to just have an idea of what to make that I forgot about the fact that I don't really like marshmallows. 

I had promised a s'mores dessert, so a s'mores dessert is what I'd make. But then came the question of what type of dessert was I going to subject to a s'mores makeover? Cookies? Ice-Cream? Cheesecake? Cake? Brownies? In the end, I ended up opting for a fudgy bar dessert. I thought I'd have the best chance at enjoying it if the marshmallows were contained to one layer of the dessert. 

I was right! To my surprise, I really enjoyed this dessert, marshmallows and all! It is so, so good. The peanuts and peanut butter are such a great flavor to add to the classic s'mores ingredients. It also is quick, easy, and fun to make! No campfire, no problem - these bars are tastier than the originals. These would also make a wonderful dessert to bring to a gathering, they're so tasty and they serve well. They are also really pretty with the toasty marshmallow and chocolate drizzle on top.

Making these is seriously so easy. First you make the crust, and pack it down tightly into your pan. I used a drinking glass to pack mine down. Then while the crust is baking combine your filling ingredients in a saucepan and melt everything together. When the crust is done baking, pour your chocolate peanut butter filling on top, add marshmallows and broil for about 2 min until the marshmallows are golden on top. Throw some graham crackers, peanuts, and chocolate drizzle on top and you're all set! Pop them in the fridge to firm up and then when you're ready to serve they can be eaten cold, room temperature, or warmed up!

Warm or cold, these bars are sure to be a hit with family and friends. A little goes a long way with these, so you could easily get 20 bars from the pan. Not saying 20 bars would feed 20 people though... It is way too easy to go back for seconds!
